Hooded Flashlight or Lens Shield Help Hide Light in Blackout
Contenuto
Two recent flashlight developments, intended to conceal the rays against visibility from above so the lamps may be used safely during a blackout, consist of a flashlight with built-in hood and a shield which may be trimmed to fit any flashlight. With the hooded flashlight, a strong beam may be aimed straight ahead, but the hood prevents side glow. The shield, attached to any ordinary flashlight, provides a window that opens or closes for a clear or subdued light. It is inserted inside the lens-holding ring, and if it does not fit exactly it may be trimmed easily with a pair of scissors to the right size.
